Surge arrester DEHNguard M TNC 275, 3-pole for 230 V AC networks 952300

Surge arrester – reliable protection of electrical installations

The DEHNguard M TNC 275 surge arrester is a key element of a system protecting against the effects of lightning strikes and overvoltages in electrical installations. Designed for mounting on a TH-35 mm DIN rail, it provides effective protection for electrical devices in TNC networks with a voltage of 230 V AC. This three-pole arrester, thanks to its construction and applied technologies, minimizes the risk of damage caused by sudden voltage increases.

DEHNguard M modular surge arresters are characterized by high impact resistance of zinc oxide varistors and the presence of a Thermo-Dynamik-Control system, which increases safety. Optical signaling (green/red) informs about the module status, and in FM models, remote damage signaling is also available. This solution facilitates quick identification and replacement of damaged elements, which translates into the continuity of the protection system.

Features and benefits for the installer and user

• Versatile application: ideal for protecting installations in residential, commercial and industrial buildings.
• Easy installation: thanks to standard dimensions (3 modules) and mounting on a TH-35 mm DIN rail, installation is quick and simple.
• High efficiency: provides a protection level of up to 1.5 kV and a short-circuit strength of up to 50 kA, protecting against the effects of even strong overvoltages.
• Energy coordination: possibility of coordination with other products from the DEHN series ensures comprehensive protection of the entire installation.
• Safety of use: the Thermo-Dynamik-Control system monitors the temperature of the varistor and reacts to current overloads, ensuring safe operation of the device.
• Status signaling: optical signaling of the module status facilitates control and quick reaction in the event of a failure.
• High current capacity: maximum cross-section of flexible conductor up to 25 mm² and stranded conductor up to 35 mm² allows connection of conductors of various thicknesses.
• Compliance with standards: meets the requirements of PN-EN 61643-11 (Type 2) and class II according to PN-IEC 61643-1, guaranteeing high quality and reliability.

The DEHNguard M TNC 275 surge arrester is an investment in the safety and durability of the electrical installation, which protects against costly failures and downtime. Its solid construction and advanced technologies ensure long-lasting and reliable protection against overvoltages.
